If "0.0" appears on the scale's display, it means that your scale isn't able to calibrate on its own. Tap the scale once before stepping on it to weigh in.
If you want to prevent this from happening every time, perform the following steps:
- Go to the settings of the online dashboard.
- Click the Devices tab.
- Click the Auto-calibration box.
Important: When using the auto-calibration feature, it is important that you wait 10 seconds after placing or moving the scale before weighing yourself as the scale needs several seconds to calibrate. You must also wait 10 seconds in between each weigh-in so that it can recalibrate.
